Check for damaged, miswired, or wrong run
capacitor
•
Check for broken wires, loose connectors, or
miswired compressor
•
Check compressor windings for continuity
•
Check for open compressor internal protector
06 – Compressor Open Start Circuit
The ICC detects current in the Run circuit
but not in the Start circuit of the compressor
•
Check for damaged, miswired, or wrong run
capacitor
•
Check for broken wires, loose connectors, or
miswired compressor
•
Check compressor windings for continuity
07 – Compressor Open Run Circuit
The ICC detects current in the Start circuit
but not in the Run circuit of the compressor
•
Check for damaged, miswired, or wrong run
capacitor
•
Check for broken wires, loose connectors, or
miswired compressor
•
Check compressor windings for continuity
09 – Low Secondary Volts
The secondary voltage at R and C is below
18VAC
•
Control transformer overloaded
•
Low line voltage
